BACKGROUND

5th generation (5G) wireless systems represent a next major phase ofmobile telecommunications standards beyond the currenttelecommunications standards of 4^(th) generation (4G). Rather thanfaster peak Internet connection speeds, 5G planning aims at highercapacity than current 4G, allowing a higher number of mobile broadbandusers per area unit, and allowing consumption of higher or unlimiteddata quantities. This would enable a large portion of the population tostream high-definition media many hours per day with their mobiledevices, when out of reach of wireless fidelity hotspots. 5G researchand development also aims at improved support of machine-to-machinecommunication, also known as the Internet of things, aiming at lowercost, lower battery consumption, and lower latency than 4G equipment.

The above-described background relating to reporting sub-band channelquality data is merely intended to provide a contextual overview of somecurrent issues, and is not intended to be exhaustive. Other contextualinformation may become further apparent upon review of the followingdetailed description.

Described herein are systems, methods, articles of manufacture, andother embodiments or implementations that can facilitate sub-bandchannel quality indicator reporting for frequency selective schedulingfor a 5G network. Facilitating sub-band channel quality indicatorreporting for frequency selective scheduling for a 5G network can beimplemented in connection with any type of device with a connection tothe communications network (e.g., a mobile handset, a computer, ahandheld device, etc.) any Internet of things (JOT) device (e.g.,toaster, coffee maker, blinds, music players, speakers, etc.), and/orany connected vehicles (cars, airplanes, space rockets, and/or other atleast partially automated vehicles (e.g., drones)). In some embodimentsthe non-limiting term user equipment (UE) is used. It can refer to anytype of wireless device that communicates with a radio network node in acellular or mobile communication system. Examples of UE are targetdevice, device to device (D2D) UE, machine type UE or UE capable ofmachine to machine (M2M) communication, PDA, Tablet, mobile terminals,smart phone, laptop embedded equipped (LEE), laptop mounted equipment(LME), USB dongles etc. Note that the terms element, elements, andantenna ports can be interchangeably used but carry the same meaning inthis disclosure. The embodiments are applicable to single carrier aswell as to multicarrier (MC) or carrier aggregation (CA) operation ofthe UE. The term carrier aggregation (CA) is also called (e.g.interchangeably called) “multi-carrier system”, “multi-cell operation”,“multi-carrier operation”, “multi-carrier” transmission and/orreception.

In some embodiments the non-limiting term radio network node or simplynetwork node is used. It can refer to any type of network node thatserves UE is connected to other network nodes or network elements or anyradio node from where UE receives a signal. Examples of radio networknodes are Node B, base station (BS), multi-standard radio (MSR) nodesuch as MSR BS, eNode B, network controller, radio network controller(RNC), base station controller (BSC), relay, donor node controllingrelay, base transceiver station (BTS), access point (AP), transmissionpoints, transmission nodes, RRU, RRH, nodes in distributed antennasystem (DAS) etc.

Cloud radio access networks (RAN) can enable the implementation ofconcepts such as software-defined network (SDN) and network functionvirtualization (NFV) in 5G networks. This disclosure can facilitate ageneric channel state information framework design for a 5G network.Certain embodiments of this disclosure can comprise an SDN controllerthat can control routing of traffic within the network and between thenetwork and traffic destinations. The SDN controller can be merged withthe 5G network architecture to enable service deliveries via openapplication programming interfaces (“APIs”) and move the network coretowards an all internet protocol (“IP”), cloud based, and softwaredriven telecommunications network. The SDN controller can work with, ortake the place of policy and charging rules function (“PCRF”) networkelements so that policies such as quality of service and trafficmanagement and routing can be synchronized and managed end to end.

To meet the huge demand for data centric applications, 4G standards canbe applied 5G, also called new radio (NR) access. 5G networks cancomprise the following: data rates of several tens of megabits persecond supported for tens of thousands of users; 1 gigabit per secondcan be offered simultaneously to tens of workers on the same officefloor; several hundreds of thousands of simultaneous connections can besupported for massive sensor deployments; spectral efficiency can beenhanced compared to 4G; improved coverage; enhanced signalingefficiency; and reduced latency compared to LTE. In multicarrier systemsuch as OFDM, each subcarrier can occupy bandwidth (e.g., subcarrierspacing). If the carriers use the same bandwidth spacing, then it can beconsidered a single numerology. However, if the carriers occupydifferent bandwidth and/or spacing, then it can be considered a multiplenumerology.

Downlink reference signals are predefined signals occupying specificresource elements within a downlink time-frequency grid. There areseveral types of downlink reference signals that can be transmitted indifferent ways and used for different purposes by a receiving terminal.Channel state information reference signals (CSI-RS) can be used byterminals to acquire channel-state information (CSI) and beam specificinformation (e.g., beam reference signal received power). In 5G, CSI-RScan be user equipment (UE) specific so it can have a significantly lowertime/frequency density. Demodulation reference signals (DM-RS), alsosometimes referred to as UE-specific reference signals, can be used byterminals for channel estimation of data channels. The label“UE-specific” relates to each demodulation reference signal beingintended for channel estimation by a single terminal. The demodulationreference signal can then be transmitted within the resource blocksassigned for data traffic channel transmission to that terminal. Otherthan the aforementioned reference signals, there are other referencesignals, namely multi-cast broadcast single frequency network (MBSFN)and positioning reference signals that can be used for various purposes.

A physical downlink control channel (PDCCH) can carry information aboutscheduling grants. Typically, this comprises a of number of multiple-inmultiple-out (MIMO) layers scheduled, transport block sizes, modulationfor each code word, parameters related to a hybrid automatic repeatrequest (HARQ), sub band locations etc. It should be noted that alldownlink control information (DCI) formats may not transmit all theinformation as shown above. In general, the contents of PDCCH can dependon a transmission mode and a DCI format. Typically, the followinginformation is transmitted by means of the DCI format: carrierindicator, identifier for dci formats, bandwidth part indicator,frequency domain resource assignment, time domain resource assignment,virtual resource block (VRB) to physical resource block (PRB) mappingflag, PRB bundling size indicator, rate matching indicator,zero-punctuation (ZP) CSI-RS trigger, modulation and coding scheme foreach transport block (TB), new data indicator for each TB, redundancyversion for each TB, HARQ process number, downlink assignment index,transaction processing benchmark (TPC) command for uplink controlchannel, physical uplink control channel (PUCCH) resource indicator,physical downlink scheduling channel to HARQ feedback timing indicator,antenna port(s), transmission configuration indication, systemrequirement specification (SRS) request, cbg transmission information,cbg flushing out information, and/or dmrs sequence initialization.

The uplink control channel can carry information aboutHARQ-acknowledgment (ACK) information corresponding to the downlink datatransmission, and channel state information. The channel stateinformation typically comprise: CRI, RI, CQI, PMI and layer indicatordata, etc. The CSI can be divided into two categories: one for sub-bandand the other for wideband. The configuration of sub-band or widebandCSI reporting can be done through RRC signaling as part of CSI reportingconfiguration. Table 1 depicts the contents of a CSI report for PMIformat indicator=Wideband, CQI format indicator=wideband and for PMIformat indicator=sub-band, CQI format indicator=sub-band.

TABLE 1 Contents of CSI report for both wideband and side bandPMI-Format Indicator = sub-band PMI or CQI-Format Indicator = sub-bandCQI PMI-Format Indicator = wideband PMI CSI Part II and CQI-FormatIndicator = wideband CQI CSI Part I wideband sub-band CRI CRI WidebandSub-band CQI for the differential second TB CQI for the second TB(transport block) of all even sub- bands Rank Indicator Rank IndicatorPMI PMI sub- wideband band (XI and X2) information fields X₂ of all evensub- bands Layer Indicator Layer Indicator — Sub-band differential CQIfor the second TB of all odd sub-bands PMI wideband (XI and X2) WidebandCQI — PMI sub- band information fields X₂ of all odd sub- bands WidebandCQI Sub-band — — differential CQI for the first TB

Note that for NR, the sub-band is defined according to the bandwidthpart of the OFDM in terms of PRBs as shown in Table 2. The sub-bandconfiguration is also done through RRC signaling.

According to the existing 5G NR standard, the UE should report sub-bandCQI as a differential CQI to reduce the uplink overhead. Thedifferential sub-band CQI can be defined. As each sub-band index s, a2-bit sub-band differential CQI can be defined as sub-band offset level(s)=wideband CQI index−sub-band CQI index (s). The mapping from the2-bit wideband differential CQI values to the offset level is shown inTable 3.

TABLE 3 Mapping sub band differential CQI value to offset level Sub banddifferential CQI value Offset level 0 0 1 1 2 ≥2  3 ≤−1  

As mentioned in the above sections, even though the UE can transmitfeedback either wideband CQI and wideband precoding matrix index (PMI),or sub-band CQI and sub-band precoding matrix index based on the RRCconfiguration of CSI reporting, when the UE is configured to reportsub-band PMI and sub-band CQI, the UE can report two bits for eachsub-band and reports differential CQI as in Table 3.

To report sub-band differential CQI from the UE, the network can providean offset value (Diff_offset) to the UE. After receiving this value, theUE can report the sub-band differential CQI according to the table 4.For each sub-band index s, a log 2(N+2)-bit sub-band differential CQIcan be defined as:Sub-band Offset level(s)=wideband CQI index−sub-band CQIindex(s)  Equation (1):

The mapping from the log 2(N+2)-bit wideband differential CQI values tothe offset level is also shown in Table 4.

TABLE 4 Proposed Mapping of sub band differential CQI value to offsetlevel Sub band differential CQI value Offset level 0 0 1 1 — — — — N − 1N ≥Diff_offset N + 1 ≤−(Diff_offset−1)

It can be understood that with the existing method of reporting sub-bandCQI, the UE can indicate the ID of the sub-band if the CQI is greaterthan 2, however the network cannot estimate the actual CQI. Hence, withthe current approach of sub-band CQI reporting, the network cannotschedule even though some sub-bands have a higher CQI compared to thewideband CQI. Thus, this can result in reduction of throughput.

The network can obtain the actual CQI information and facilitatesub-band scheduling for achieving frequency selective gains. The UE canuse 4-bit CQI for all of the sub-bands rather than using differentialCQI. In another embodiment, the UE can extend the differential CQI table(e.g., variable offset value) such that it can report the sub-band CQIs.The disclosure comprises multiple embodiments, which can be implementedboth at the network node and at the UE (e.g., a method at the UE toreport sub band CQI using full resolution, a method at the UE to reportsub band CQI using pre-defined offset value, a method at the UE toreport sub band CQI using RRC configured offset value, etc.).

In one embodiment, the network can indicate the offset value using anRRC configuration as part of CSI report setting. In another embodiment,the network can use physical layer signaling such as downlink controlchannel information (DCI) or physical downlink control channel (PDCCH)orders for indicating the offset value. In another embodiment, apre-defined value (e.g., Diff_offset) can be used (e.g., the network andthe UE have the same understanding of the value).

The network can set the value of Diff_offset and communicate to the UE.The network can send a higher offset value if any one or more conditionsare satisfied. For example, for a configured bandwidth part (BWP), thenetwork can choose a higher value of Diff_offset if the configured BWPis higher and vice versa. As the bandwidth is larger, there is a highprobability that the CQI variation is more across the sub-bands. Hence,the network can choose the offset based on the BWP.

Another technique can comprise utilizing the number of CSI-RS ports. Inthis technique, the network can choose a higher value if the number ofCSI-RS ports is greater and vice versa. For example, if the number ofCSI-RS ports is 8, the network can choose an offset value equal to 4.However, if the number of CSI-RS ports is 2, the network can choose andoffset value of 2. Thus, the more transmit antennas, the more frequencyselectivity.

The network can choose a higher value based on past sub-band CQIreports. In this technique, if the past sub-band reports indicate asignificant number of sub-bands, then the network can indicate a highervalue of sub-bands and CQI. The network can choose the offset valuebased on the computed sub-band CQI from the UE (e.g., uplink sub-bandCQI). In this scenario, reciprocity can be assumed wherein the downlinkchannel can be estimated from the CQI of the uplink channel.Additionally, any the network can also utilize any combination of theaforementioned techniques to determine the offset value.

Furthermore, a method for reporting sub-band CQI of 4 bits can beleveraged by the UE. In this technique, instead of using differentialCQI for each sub band, the network can use a full resolution (e.g., 4bits) of CQI similar to a wideband CQI. For example, the network caninform the UE to report 4-bit CQI for each sub band. The aforementionedsignaling techniques for determining the offset value and for sendingthe communication to the UE about the 4-bit sub-band CQI can also beused. In another embodiment, the network and the UE can have a commonunderstanding that for aperiodic CSI reports, a physical uplink sharedchannel can be used with 4-bit sub-band CQI. However, for periodic CSIreports, the network and UE can utilize a physical uplink controlchannel and choose a differential CQI for each sub-band.

In one embodiment, described herein is a method comprising receiving, bya mobile device comprising a processor, instruction data representativeof an instruction to select a provisional channel quality indicator froma network device of a wireless network based on aperiodic channelquality data associated with a sub-band, wherein the instruction data isbased on a configured bandwidth part associated with a communicationbetween the network device and the mobile device, and wherein a channelquality indicator comprises a full resolution associated with thesub-band. The method also comprises in response to the receiving, by themobile device, selecting the provisional channel quality indicator basedon the instruction data. Furthermore, in response to the selecting, themethod can comprise facilitating, by the mobile device, sending thechannel quality indicator to the network device in accordance with afull resolution instruction associated with the full resolution.

According to another embodiment, a network device can facilitate,selecting a differential offset value representative of a differentialoffset channel of the wireless network based on a condition associatedwith channel quality data of a sub-band of a wireless network beingdetermined to have been satisfied. The network device can alsofacilitate sending the differential offset value to a mobile device ofthe wireless network. Additionally, the network device operations cancomprise receiving data from the mobile device via a channel between themobile device and the network device in response to the sending thedifferential offset value to the mobile device.

According to yet another embodiment, described herein is amachine-readable storage medium that can perform the operationscomprising selecting a differential offset value representative of adifferential offset based on a condition associated with periodicchannel state data associated with a sub-band of the wireless networkbeing determined to have been satisfied. The machine-readable storagemedium can perform the operations comprising facilitating sending, to amobile device of the wireless network, the differential offset value.Furthermore, the machine-readable storage medium can perform theoperations comprising facilitating sending a differential sub-bandchannel quality indicator from the mobile device via a physical uplinkcontrol channel in accordance with the differential offset in responseto the facilitating the sending the differential offset value to themobile device.

The embodiments areapplicable to single carrier as well as to multicarrier (MC) or carrieraggregation (CA) operation of the UE. The term carrier aggregation (CA)is also called (e.g. interchangeably called) “multi-carrier system”,“multi-cell operation”, “multi-carrier operation”, “multi-carrier”transmission and/or reception. Note that some embodiments are alsoapplicable for Multi RAB (radio bearers) on some carriers (that is dataplus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide andemploy 5G wireless networking features and functionalities. 5G wirelesscommunication networks are expected to fulfill the demand ofexponentially increasing data traffic and to allow people and machinesto enjoy gigabit data rates with virtually zero latency. Compared to 4G,5G supports more diverse traffic scenarios. For example, in addition tothe various types of data communication between conventional UEs (e.g.,phones, smartphones, tablets, PCs, televisions, Internet enabledtelevisions, etc.) supported by 4G networks, 5G networks can be employedto support data communication between smart cars in association withdriverless car environments, as well as machine type communications(MTCs). Considering the drastic different communication needs of thesedifferent traffic scenarios, the ability to dynamically configurewaveform parameters based on traffic scenarios while retaining thebenefits of multi carrier modulation schemes (e.g., OFDM and relatedschemes) can provide a significant contribution to the highspeed/capacity and low latency demands of 5G networks. With waveformsthat split the bandwidth into several sub-bands, different types ofservices can be accommodated in different sub-bands with the mostsuitable waveform and numerology, leading to an improved spectrumutilization for 5G networks.

To meet the demand for data centric applications, features of proposed5G networks may comprise: increased peak bit rate (e.g., 20 Gbps),larger data volume per unit area (e.g., high system spectralefficiency—for example about 3.5 times that of spectral efficiency oflong term evolution (LTE) systems), high capacity that allows moredevice connectivity both concurrently and instantaneously, lowerbattery/power consumption (which reduces energy and consumption costs),better connectivity regardless of the geographic region in which a useris located, a larger numbers of devices, lower infrastructuraldevelopment costs, and higher reliability of the communications. Thus,5G networks may allow for: data rates of several tens of megabits persecond should be supported for tens of thousands of users, 1 gigabit persecond to be offered simultaneously to tens of workers on the sameoffice floor, for example; several hundreds of thousands of simultaneousconnections to be supported for massive sensor deployments; improvedcoverage, enhanced signaling efficiency; reduced latency compared toLTE.

The upcoming 5G access network may utilize higher frequencies (e.g., >6GHz) to aid in increasing capacity. Currently, much of the millimeterwave (mmWave) spectrum, the band of spectrum between 30 gigahertz (Ghz)and 300 Ghz is underutilized. The millimeter waves have shorterwavelengths that range from 10 millimeters to 1 millimeter, and thesemmWave signals experience severe path loss, penetration loss, andfading. However, the shorter wavelength at mmWave frequencies alsoallows more antennas to be packed in the same physical dimension, whichallows for large-scale spatial multiplexing and highly directionalbeamforming.

Performance can be improved if both the transmitter and the receiver areequipped with multiple antennas. Multi-antenna techniques cansignificantly increase the data rates and reliability of a wirelesscommunication system. The use of multiple input multiple output (MIMO)techniques, which was introduced in the third-generation partnershipproject (3GPP) and has been in use (including with LTE), is amulti-antenna technique that can improve the spectral efficiency oftransmissions, thereby significantly boosting the overall data carryingcapacity of wireless systems. The use of multiple-input multiple-output(MIMO) techniques can improve mmWave communications, and has been widelyrecognized a potentially important component for access networksoperating in higher frequencies. MIMO can be used for achievingdiversity gain, spatial multiplexing gain and beamforming gain. Forthese reasons, MIMO systems are an important part of the 3rd and 4thgeneration wireless systems, and are planned for use in 5G systems.

Referring now to FIG. 2 , illustrated is an example schematic systemblock diagram of a message sequence chart between a network node anduser equipment according to one or more embodiments.

FIG. 2 depicts a message sequence chart for downlink data transfer in 5Gsystems 200. The network node 106 can transmit reference signals to auser equipment (UE) 102. The reference signals can be cell specificand/or user equipment 102 specific in relation to a profile of the userequipment 102 or some type of mobile identifier. From the referencesignals, the user equipment 102 can compute channel state information(CSI) and compute parameters needed for a CSI report at block 202. TheCSI report can comprise: a channel quality indicator (CQI), a pre-codingmatrix index (PMI), rank information (RI), a CSI-resource indicator(e.g., CRI the same as beam indicator), etc.

The user equipment 102 can then transmit the CSI report to the networknode 106 via a feedback channel either on request from the network node106, a-periodically, and/or periodically. A network scheduler canleverage the CSI report to determine downlink transmission schedulingparameters at 204, which are particular to the user equipment 102. Thescheduling parameters 204 can comprise modulation and coding schemes(MCS), power, physical resource blocks (PRBs), etc. FIG. 2 depicts thephysical layer signaling where the density change can be reported forthe physical layer signaling or as a part of the radio resource control(RRC) signaling. In the physical layer, the density can be adjusted bythe network node 106 and then sent over to the user equipment 102 as apart of the downlink control channel data. The network node 106 cantransmit the scheduling parameters, comprising the adjusted densities,to the user equipment 102 via the downlink control channel. Thereafterand/or simultaneously, data can be transferred, via a data trafficchannel, from the network node 106 to the user equipment 102.

Referring now to FIG. 3 , illustrated is an example schematic systemblock diagram of a coding chain for a physical downlink shared channeltransmitter according to one or more embodiments. FIG. 3 depicts thetransmission side of a MIMO communication system 300 with N_(t) transmitantennas. There are up to 2 transport blocks 302, 304 where the numberof transport blocks can be equal to one when the number of layers isless than or equal to 4. If the number of layers is more than 4, then 2transport blocks can be transmitted. The cyclic redundancy check (CRC)bits can be added to each transport block and passed to the channelencoder 306, 308. Low-density parity check codes (LDPC) can be used forforward error correction (FEC) in NR. The channel encoder 306, 308 canadd parity bits to protect the data. After encoding, the data stream canbe scrambled with user-specific scrambling. Then the stream can bepassed through an interleaver 310, 312.

The interleaver size can be adaptively controlled by puncturing toincrease the data rate. The adaptation can be performed by using theinformation from the feedback channel (e.g., channel state informationsent by the receiver). The interleaved data can be passed through asymbol mapper (modulator). The symbol mapper can also be controlled bythe adaptive controller 326, after the modulator streams are passedthrough a layer mapper 314 and the precoder 316. The resultant symbolscan be mapped at re-mappers 318, 320 to the resource elements in atime-frequency grid of OFDM. The resultant streams can then be passedthrough an inverse fast fourier transform (IFFT) block 322, 324. Itshould be noted that in some systems, the IFFT block may not benecessary and can be dependent on the multiple access system. Theencoded stream can then be transmitted through the respective antenna.

Since the bandwidth is very large, thevariation in the reported signal interference to noise ratio (SINR) isincreased. Thus, a more efficient solution can achieve frequencyselective scheduling gains in 5G systems.
